A Perspective on Adult Corrections in Washington

Any proposals for reform of Washington\u27s correctional process must be evaluated in the context of factual information concerning the present system. This comment will familiarize those interested in correctional issues with the legal and institutional framework of the Washington system. The first section of the comment describes the course of events experienced by an adult offender immediately after conviction of a felony, whether upon a guilty plea or by a verdict of guilty following a trial. It examines the probation decision, the sentencing process, the institutions, and the parole considerations for those offenders subject to the correctional system. The second section of the comment analyzes available statistical information on certain aspects of the Washington correctional process, including the increased use of probation, the nature of institutional populations, and the likelihood of a paroled offender returning to the correctional system

Prolactin delays hair regrowth in mice

Mammalian hair growth is cyclic, with hair-producing follicles alternating between active (anagen) and quiescent (telogen) phases. The timing of hair cycles is advanced in prolactin receptor (PRLR) knockout mice, suggesting that prolactin has a role in regulating follicle cycling. In this study, the relationship between profiles of circulating prolactin and the first post-natal hair growth cycle was examined in female Balb/c mice. Prolactin was found to increase at 3 weeks of age, prior to the onset of anagen 1 week later. Expression of PRLR mRNA in skin increased fourfold during early anagen. This was followed by upregulation of prolactin mRNA, also expressed in the skin. Pharmacological suppression of pituitary prolactin advanced dorsal hair growth by 3.5 days. Normal hair cycling was restored by replacement with exogenous prolactin for 3 days. Increasing the duration of prolactin treatment further retarded entry into anagen. However, prolactin treatments, which began after follicles had entered anagen at 26 days of age, did not alter the subsequent progression of the hair cycle. Skin from PRLR-deficient mice grafted onto endocrine-normal hosts underwent more rapid hair cycling than comparable wild-type grafts, with reduced duration of the telogen phase. These experiments demonstrate that prolactin regulates the timing of hair growth cycles in mice via a direct effect on the skin, rather than solely via the modulation of other endocrine factors

Multi-neutron transfer coupling in sub-barrier 32S+90,96Zr fusion reactions

The role of neutron transfers is investigated in the fusion process below the Coulomb barrier by analyzing 32S+90Zr and 32S+96Zr as benchmark reactions. A full coupled-channel calculation of the fusion excitation functions has been performed for both systems by using multi-neutron transfer coupling for the more neutron-rich reaction. The enhancement of fusion cross sections for 32S+96Zr is well reproduced at sub-barrier energies by NTFus code calculations including the coupling of the neutron-transfer channels following the Zagrebaev semiclassical model. We found similar effects for 40Ca+90Zr and 40Ca+96Zr fusion excitation functions.Comment: Minor corrections, 11 pages, 4 figures, Fusion11 Conference, Saint Malo, France, 2-6 mai 201

Is tagging with visual implant elastomer a reliable technique for marking earthworms?

Visual implant elastomer (VIE) has recently been employed to investigate different aspects of earthworm ecology. However, a number of fundamental questions relating to the detection and positioning of the tag, its persistence and potential effects on earthworms remain unknown. Seven earthworm species belonging to three ecological groupings, with different pigmentation and burrowing behaviour, were tagged using different coloured VIE. External inspection after two days, one week and 1, 10 and 27 months were followed by preservation, dissection and internal inspection. Tags could be seen in living specimens to 27 months, and dissection revealed that in most cases they were lodged in the coelomic cavity, held in place by septa. However, over longer time periods (more than two years), the chlorogogenous tissue tended to bind to the tags and made external observation increasingly difficult. Migration of the VIE material towards the posterior of the earthworm and potential loss of the tag were only observed on rare occasions, and a recovery rate in excess of 98% was recorded. By introducing a reasonable amount of VIE into segments, just after the clitellum, this technique can become a valuable tool in earthworm ecology and life history studies, particularly in short-medium term laboratory and field experiments

In Vitro Growth Characteristic and Microbial Community Dynamic of Atlantic Salmon (Salmo Salar L) Gastrointestinal Tract in Relation to the Different Diet Formulations

In order to better understand microbial changes within the salmon gastrointestinal tract as determined at the dietary level, the microbial community dynamics were assessed within a simple in vitro growth model system. In this system the growth and composition of bacteria were monitored within diet slurries held under anaerobic conditions inoculated with salmon faecal samples. This system was assessed using total viable bacteria counts (TVC), automated ribosomal intergenic spacer analysis (ARISA) and 16S rRNA pair-end Illumina-based sequence analysis

Timing of restoration of bowel continuity after decompressing stoma, in left-sided obstructive colon cancer:a nationwide retrospective cohort

BACKGROUND: With the increasing use of decompressing stoma as a bridge to surgery for left-sided obstructive colon cancer (LSOCC), the timing of restoration of bowel continuity (ROBC) is a subject of debate. There is a lack of data on immediate ROBC during elective resection as an alternative for a 3-stage procedure. This study analysed if immediate ROBC during tumour resection is safe and of any benefit for patients who underwent decompressing stoma for LSOCC. METHODS: In a Dutch nationwide collaborative research project, 3153 patients who underwent resection for LSOCC in 75 hospitals (2009-2016) were identified. Extensive data on disease and procedural characteristics, and outcomes was collected by local collaborators. For this analysis, 332 patients who underwent decompressing stoma followed by curative resection were selected. Immediate ROBC during tumour resection was compared to two no immediate ROBC groups, (1) tumour resection with primary anastomosis (PA) with leaving the decompressing stoma in situ, and (2) tumour resection without PA. RESULTS: Immediate ROBC was performed in 113 patients (34.0%) and no immediate ROBC in 219 patients [168 with PA (50.6%) and 51 patients without PA (15.4%)]. No differences at baseline between the groups were found for age, ASA score, cT, and cM. Major surgical complications (8.8% immediate ROBC vs. 4.8% PA with decompressing stoma and 7.8% no PA; P =0.37) and mortality (2.7% vs. 2.4% and 0%, respectively; P =0.52) were similar. Immediate ROBC resulted in a shorter time with a stoma (mean 41 vs. 240 and 314 days, respectively; P &lt;0.001), and fewer permanent stomas (7% vs. 21% and 80%, respectively; P &lt;0.001) as compared to PA with a decompressing stoma or no PA. CONCLUSION: After a decompressing stoma for LSOCC, immediate ROBC during elective resection appears safe, reduces the total time with a stoma and the risk of a permanent stoma.</p

Genomic surveillance of 4CMenB vaccine antigenic variants among disease-causing Neisseria meningitidis isolates, United Kingdom, 2010–2016

In September 2015, 4CMenB meningococcal vaccine was introduced into the United Kingdom infant immunization program without phase 3 trial information. Understanding the effect of this program requires enhanced surveillance of invasive meningococcal disease (IMD) Neisseria meningitidis isolates and comparison with prevaccination isolates. Bexsero Antigen Sequence Types (BASTs) were used to analyze whole-genome sequences of 3,073 prevaccine IMD N. meningitidis isolates obtained during 2010−2016. Isolates exhibited 803 BASTs among 31 clonal complexes. Frequencies of antigen peptide variants were factor H binding protein 1, 13.4%; Neisserial heparin-binding antigen 2, 13.8%; Neisseria adhesin A 8, 0.8%; and Porin A-VR2:P1.4,10.9%. In 2015−16, serogroup B isolates showed the highest proportion (35.7%) of exact matches to &#62;1 Bexsero components. Serogroup W isolates showed the highest proportion (93.9%) of putatively cross-reactive variants of Bexsero antigens. Results highlighted the likely role of cross-reactive antigens. BAST surveillance of meningococcal whole-genome sequence data is rapid, scalable, and portable and enables international comparisons of isolates

Segregation effects on the properties of (AuAg)147

AuAg nanoclusters are promising supported co-catalysts for photocatalytic hydrogen reduction. However, beyond the quantum regime (N > 100) little is known about how the electronic properties of these nanoparticles are affected by chemical ordering. We investigate the effects of chemical ordering on the properties of 147-atom cuboctahedral AuAg nanoclusters, using empirical potentials coupled with an atomic-swap basin-hopping search to optimise the elemental distribution, with the lowest energy arrangements then reminimised using Density Functional Theory (DFT). Force-field calculations show Au atoms preferentially occupy sub-surface positions in the bimetallic structures, which results in the formation of a pseudo-onion structure for Ag-rich compositions. At the DFT-level, however, an Ag core surrounded by an Au shell (Ag@Au) is energetically favoured, as electron density can be drawn more readily when Au atoms are positioned on the nanocluster surface, thus resulting in a partial negative charge. Core@shell configurations are analogous to structures that can be chemically synthesised, and further detailed electronic analysis is discussed in the context of nanocluster applications to co-catalysed photocatalysis

The mediating effect of task presentation on collaboration and children's acquisition of scientific reasoning

There has been considerable research concerning peer interaction and the acquisition of children's scientific reasoning. This study investigated differences in collaborative activity between pairs of children working around a computer with pairs of children working with physical apparatus and related any differences to the development of children's scientific reasoning. Children aged between 9 and 10 years old (48 boys and 48 girls) were placed into either same ability or mixed ability pairs according to their individual, pre-test performance on a scientific reasoning task. These pairs then worked on either a computer version or a physical version of Inhelder and Piaget's (1958) chemical combination task. Type of presentation was found to mediate the nature and type of collaborative activity. The mixed-ability pairs working around the computer talked proportionally more about the task and management of the task; had proportionally more transactive discussions and used the record more productively than children working with the physical apparatus. Type of presentation was also found to mediated children's learning. Children in same ability pairs who worked with the physical apparatus improved significantly more than same ability pairs who worked around the computer. These findings were partially predicted from a socio-cultural theory and show the importance of tools for mediating collaborative activity and collaborative learning
